[0023] See also Figure 1 - Figure 5As shown, a security monitoring pole support lifting structure includes a monitoring body 1, a lifting rod 20 and a pole body 21. A through hole 35 is provided at the top of the pole body 21, and the diameter of the through hole 35 is slightly larger than that of the lifting rod 20; a lifting assembly is arranged inside the pole body 21, and the lifting assembly includes a gear 24, a driving motor 25 is fixedly connected to the rear end of the gear 24, and the bottom end of the driving motor 25 is welded and fixed to a support plate 26, and the support plate 26 is welded and fixed to the inner wall of the pole body 21, and a plurality of grooves 22 are provided on the right side of the gear 24. A round block 23 is welded and fixed on the bottom end of the lifting rod 20. The diameter of the round block 23 is larger than that of the lifting rod 20. The bottom end of the round block 23 contacts the inner wall of the upright body 21. A clamping assembly is arranged on the top of the upright body 21. The clamping assembly includes two groups of clamping blocks 33. The bottom ends of the clamping blocks 33 are rotatably connected to the fixed block 34. Slide grooves 27 are provided on both the front and rear sides of the lifting rod 20. The slide grooves 27 are designed in a long rectangular shape. A plurality of groups of clamping grooves 28 are provided on the inner wall of the slide groove 27. The clamping grooves 28 are designed in a rectangular shape and are adapted to the size of the top of the clamping block 33.

[0024] When working, one of the above technologies is used for the lifting structure of the security monitoring pole bracket, and the rotation of the screw rod body drives the lifting of the screw rod nut, so that the monitoring body is lowered to a suitable position for inspection and maintenance. However, since the entire driving rod is long, the speed of the monitoring body descending and ascending will be slow, which consumes more time. Through the structural design of the lifting component, the function of quickly ascending and descending the lifting rod 20 is realized. When the lifting rod 20 is to be lifted, the gear 24 is first driven to rotate by the driving motor 25. The gear 24 and the multiple groups of grooves 22 opened on the lifting rod 20 are kept in meshing. The rotation of the gear 24 will cause the lifting rod 20 to move upward, so that the lifting rod 20 is directly driven by the gear 24 to complete the lifting operation, so that the lifting rod 20 can quickly complete the lifting to reduce the time for inspection and maintenance, wherein a round block 23 is fixed to the bottom end of the lifting rod 20, and the round block 23 is used to prevent the lifting rod 20 from being drawn out from the inside of the pole body 21;

[0025] Through the structural design of the locking assembly, the two groups of blocks 33 will lock with the slots 28 and achieve the function of providing support and fixation for the lifting rod 20 through the abutment between the blocks 33 and the inner walls of the slots 28, so as to keep the position height of the lifting rod 20 fixed. After the lifting rod 20 rises to an appropriate height, the two groups of blocks 33 can fix the lifting rod 20 by locking with the slots 28.

[0026] Furthermore, a torsion spring 37 is sleeved inside the fixing block 34, and the fixing block 34 is welded and fixed on the top of the upright body 21;

[0027] During operation, the torsion spring 37 sleeved inside the fixing block 34 ensures that the clamping block 33 can always maintain the clamping engagement with the clamping slot 28 , so as to facilitate the clamping and fixing between the clamping block 33 and the clamping slot 28 .

[0028] Furthermore, a pulley 31 is slidably connected inside the slide groove 27, and the pulley 31 is welded and fixed on the fixing frame 29. The top and bottom ends of the fixing frame 29 are fixed on the inner wall of the upright body 21. Two sets of notches 30 are opened at the bottom end of the round block 23;

[0029] During operation, the top of the fixing frame 29 is fixed to the inner wall of the upright body 21 by welding, and the bottom of the fixing frame 29 is fixed by bolts. The pulley 31 on the fixing frame 29 can reduce the shaking of the lifting rod 20 during the movement of the lifting rod 20, so that the lifting rod 20 is more stable when moving.

[0030] Furthermore, the inner wall of the notch 30 is in contact with the fixing frame 29, and the bottom end of the fixing frame 29 is designed in an L-shape to facilitate fixing by bolts;

[0031] During operation, the contact between the inner wall of the notch 30 and the fixing frame 29 can reduce the shaking of the lifting rod 20 in the left and right directions, thereby ensuring the meshing between the gear 24 and the groove 22 .

[0032] Furthermore, a gasket 32 ​​is glued and fixed on the top of the round block 23, and the gasket 32 ​​is made of rubber;

[0033] During operation, the gasket 32 ​​is used to buffer the top of the round block 23 and the top of the inner wall of the upright body 21 to prevent the round block 23 from directly contacting the inner wall of the upright body 21 when the lifting rod 20 rises to the maximum height.

[0034] Furthermore, a rubber ring 36 is glued and fixed on the inner wall of the through hole 35, and the rubber ring 36 and the lifting rod 20 are kept in contact;

[0035] During operation, the rubber ring 36 and the lifting rod 20 maintain contact, thereby preventing external dust and debris from entering the interior of the upright rod body 21 through the through hole 35 .

[0036] Working principle: One of the above technologies is used for the lifting structure of the security monitoring pole bracket, and the rotation of the screw rod body drives the lifting of the screw rod nut, so that the monitoring body is lowered to a suitable position for inspection and maintenance. However, since the entire driving rod is long, the speed of the monitoring body descending and ascending will be slow, which consumes more time. Through the structural design of the lifting component, the function of quickly ascending and descending the lifting rod 20 is realized. When the lifting rod 20 is to be lifted, the gear 24 is first driven to rotate by the driving motor 25. The gear 24 and the multiple groups of grooves 22 opened on the lifting rod 20 are kept in meshing. The rotation of the gear 24 will cause the lifting rod 20 to move upward, so that the lifting rod 20 is directly driven by the gear 24 to complete the lifting operation, so that the lifting rod 20 can quickly complete the lifting to reduce the time for inspection and maintenance, wherein a round block 23 is fixed to the bottom end of the lifting rod 20, and the round block 23 is used to prevent the lifting rod 20 from being drawn out from the inside of the pole body 21;

[0037] Through the structural design of the locking assembly, the two groups of blocks 33 will lock with the slots 28 and achieve the function of providing support and fixation for the lifting rod 20 through the abutment between the blocks 33 and the inner walls of the slots 28, so as to keep the position height of the lifting rod 20 fixed. After the lifting rod 20 rises to a suitable height, the two groups of blocks 33 can fix the lifting rod 20 by locking with the slots 28, wherein the blocks 33 are rotatably connected to the fixing blocks 34 and a torsion spring 37 is also sleeved inside the fixing blocks 34, so that the top of the blocks 33 can be better locked and fixed with the slots 28.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
